Scherzinger

Scherzinger is a leading German manufacturer of precision gear pumps, magnetically coupled pump assemblies and flow dividers for the dosing, measurement and transport of thin to viscous fluids in the chemical industry, laboratory technology and process industries. With a catalog of 956 products, Scherzinger supplies gear pumps in material versions of stainless steel, Hastelloy C-22 and PEEK for corrosive, toxic and flammable media. All Scherzinger pumps are available in sanitary versions for pharmaceutical production processes, including versions compliant with FDA guidelines for GMP-certified production lines.

Scherzinger gear pumps (5040-series) are the core products for precise fluid dosing and flow measurement. The 5040-350-ZK90-160-series are Hastelloy gear pumps designed for transport of strongly corrosive media such as hydrochloric acid, sulfuric acid and organic acids. Hastelloy C-22 material choice offers superior corrosion resistance in oxidizing and reducing acid environments compared to standard stainless steel (316L). Flow capacities from 0.04 to 50 liters per minute and pressures up to 100 bar are available depending on pump size.

Scherzinger magnetically coupled gear pumps (4030-450-series and externally coupled 201922 models) eliminate the shaft seal by using a hermetically sealed magnetic coupling. Magnetic coupling prevents leakage of hazardous, toxic or valuable fluids and is required in many chemical processes where fluid emissions are unacceptable. Magnetically coupled pumps are ATEX-certified for use with flammable fluids (Zone 1/2) without the risk of shaft seal leakages. The magnetic coupling is designed for a service life of more than 10 years under correct operating conditions and requires no periodic maintenance.

Scherzinger magnetic coupling assemblies (120532, 120533-series) are available as separate coupling components for installation in customer-specific pump housings. The Bell G7 magnetic coupling sets (Ø14, 2.2 Nm) are designed for smaller flow applications in laboratory equipment and analytical instruments. Flow dividers (20920 DM/EX/HF-series) accurately divide one incoming fluid flow across multiple output channels for balanced multi-point dosing systems.

At Verkopershulp.nl you will find the complete Scherzinger range including gear pumps, magnetically coupled pump assemblies, magnetic coupling assemblies, flow dividers and overhaul kits for a wide range of applications in the chemical, pharmaceutical and petrochemical industries. Our technical experts support you in material selection and pump choice for your specific fluid and process conditions, including pressure drop calculation and flow sizing for the correct pump selection.

History

Scherzinger Pump Technology GmbH was founded in 1957 in Furtwangen, Germany, in the Black Forest, as a manufacturer of precision gear pumps for industrial and scientific applications. The company specialized early in developing pump solutions for aggressive and hazardous fluids that rapidly attack standard pump materials. In the 1980s, Scherzinger was among the first to introduce Hastelloy gear pumps for the chemical and petrochemical industries, setting a new standard for corrosion-resistant fluid transport and establishing long-term partnerships with leading chemical manufacturers. Scherzinger was a pioneer in magnetically coupled gear pumps for the chemical industry. The company has maintained its production facilities in Furtwangen, Germany and is active in more than 50 countries through an international network of specialized distributors.

Frequently Asked Questions

Why is Hastelloy better than stainless steel for corrosive media? ▾
Hastelloy C-22 is a nickel-molybdenum-chromium alloy that offers superior corrosion resistance in oxidizing acids (nitric acid, chromic acid) and reducing acids (hydrochloric acid, sulfuric acid) compared to stainless steel (316L). Stainless steel 316L is susceptible to pitting corrosion and crevice corrosion in chloride-containing media; Hastelloy is virtually immune to this. Scherzinger 5040-series Hastelloy gear pumps are the correct choice for strongly acidic or mixed acid environments.
What is the advantage of a magnetically coupled pump over a mechanically sealed pump? ▾
A magnetically coupled pump has no shaft seal because the motor shaft and rotor shaft are magnetically coupled through a hermetically sealed housing. This eliminates the risk of leakage via shaft seals, which is essential with toxic, flammable or valuable fluids. Magnetically coupled pumps require no maintenance of shaft seals and are more reliable in applications where leakage is unacceptable.
How do I select the correct Scherzinger pump for my chemical application? ▾
For selecting a Scherzinger pump you need the required flow rate (ml/min or l/min), maximum working pressure, fluid viscosity, fluid type (chemical composition) and operating temperature. Based on the fluid type, the pump material is determined: stainless steel 316L for mild media, Hastelloy C-22 for strong acids and oxidative fluids, PEEK for fluorine-containing media. Our experts help you with material selection.
Are Scherzinger pumps suitable for ATEX zones? ▾
Yes, Scherzinger magnetically coupled gear pumps are available in ATEX-certified versions for use with flammable fluids in Zone 1 and Zone 2. The magnetic seal eliminates the risk of shaft leakage that can be an ignition source with a mechanically sealed pump. ATEX versions are marked II 2G and are certified conforming to ATEX Directive 2014/34/EU.
What is a flow divider and how is it applied? ▾
A Scherzinger flow divider (20920 DM/EX/HF-series) accurately divides one incoming fluid flow across multiple equal output channels (2, 4, 6 or 8 channels) for multi-point dosing systems in process industries. The flow division is based on equal resistance in all channels via precisely dimensioned metering discs. Flow dividers are available for flows from 10 ml/min to 10 l/min and fluids from 1 to 1,000 cSt viscosity.
Are Scherzinger overhaul kits available for older pumps? ▾
Yes, Scherzinger supplies overhaul kits (201926-series) including gears, bearings, seals and O-rings for overhauling worn Scherzinger gear pumps in the field. The overhaul kit is type-specific and contains all wear parts for a complete pump overhaul. After overhaul with a Scherzinger overhaul kit, the pump performs equivalently to a new pump in terms of flow accuracy and pressure build-up.
